Recent studies have provided observational support for the paradigm that solar eruptions result from the interplay between magnetic reconnection and the approximate magnetic helicity conservation in the corona: confined flares are regarded as reconnection events while CMEs are the valves through which the Sun gets rid of excess helicity. However, several aspects of the paradigm need clarification and possibly modification. The instruments onboard the "Solar Orbiter" mission will provide a unique opportunity for such work. In this article, I propose how to exploit the capabilities of the "Solar Orbiter" remote sensing instruments in order to shed more light on the processes leading to flares and CMEs.
